I've calculated some simple proportions for time distances and incremented percentage price, between the 1º and the 2º halvings. Then I related the results for similar proportions between the 2º and the 3º halving. ATH is All Time High(s).
1) DAYS: First and Second halvings: 525 / 364 ≈ 1.44
Second and Third halvings: x days for next ATH / 532 ≈ 1.44 x = 1.44 * 525 ≈ 756 days
2) PRICE: First and Second halvings: 3,854 % / 10,758 % ≈ 0.35
Second and Third halvings: x % increment / 3,854 % ≈ 0.35 x = 0.35 * 3,854 % ≈ 1,348 % which is an increment to the price of USD 130k
This numbers make sense since the supply has been reduced to half.
Next halvings is suppose to happen on February 29th, 2024. The supply will be reduced them from 6.25 to 3.125 BTC per block.
I Do not think Bitcoin will even revisit 20k this year as I believe that occurred in the past due to widespread adoption/media attention given to Bitcoin in the past that will not repeat. Most people in Bitcoin right now do not even see it as a store of value or money they are just in it to make money. I think in next 14 days this will happen (detailed explanations if you click on chart)
